Acid Etching Metal is the process of cutting into a metal surface using acid. Metal etching is used as an industrial manufacturing application, an art technique, and a application for identifying and branding property.

The Method of Acid Etching Metal

acid etching metalThe basic method for acid metal etching is to apply protection to the areas of a metal surface, either to the whole area or just to the areas that are to remain unaffected. The parts of the metal to be etched are then either not covered or the protected material is scratched off from it using tools such as an etching needle. The metal surface is then dipped in acid which then eats away at the exposed areas of the metal, creating lines.

Chemical Milling is another phrase used for industrial acid metal etching. Industrial uses include the fabrication of semiconductors, the printed circuit board industry, and by the aerospace industry in fashioning aircraft components.
